Okay Iīm now so confused about turbos, P-trim, Q-trim, 60-1 etc that iīm about to get sick!!

Hereīs all info I have of my turbo:
TO4B
60-1
A/R 1,15

I went to the www.turbonetics.com and found alot of information but my english isnīt that good and the subject is something I donīt know a **** so please help me. I also did a search but didnīt do much good, made me more confused.

So the compressor housing is TO4B?
T4 turbine section is 60-1?
What are P-trim,Q-trim or does these mean same thing as 60-1?

There are T-series and 60 series?? and my turbo is TO4B 60-1?

So the final question is WHAT TURBO DO I HAVE?

PLEASE somebody or everybody help me

 

The 60-1 is the compressor wheel, its native compressor housing is the T04S housing with a 4" inlet, when placed in a T04B housing it is usually refered to as a 60-1hifi.

The O,P,Q are the t4 series exhaust wheels, listed there from smallest to largest.

Your turbo is a 60-1hifi, most likley it has a Ptrim exhaust wheel. Not a bad turbo at all.

 

That is not quite correct.

The T04B60-1 can be had in BOTH full and HiFi versions. The only difference is that the HiFi has a 2.75" compressor inlet, and the full has a 4" inlet.

The "full" would be a T04S compressor cover. There is no T04B compressor housing with a 4" inlet.

 

Well, whatever you want to call it, I know you can buy a:

T04B 60-1 with a 4" compressor inlet and .96A/R divided turbine housing from Turbonetics.

 

My mistake, the .96 is undivided.
